  • The objective of this study was to evaluate the quality characteristics of mungbean starch gels that were prepared with different concentrations (0, 0.5, 1.0 and 1.5%) of peach seed powders (PSP), which exhibit antioxidant characteristics. Mungbean starch gel samples were prepared and subjected to quality characteristics such as moisture content, general components, color, texture profile analysis, total polyphenol contents, DPPH radical scavenging activity, and sensory qualities. The L-value and the a-value for color decreased significantly, whereas the b-value increased significantly as the PSP concentration increased (p<0.05). In the texture profile analysis, the mungbean starch gel with 1.5% PSP showed significantly lower degrees of hardness, cohesiveness, springiness, gumminess and brittleness (p<0.05). The total polyphenol content was highest in the 1.5% PSP to which mungbean starch gel was added, which also showed a higher than 70% DPPH radical scavenging activity level in a dose-dependent manner (p<0.05). In the sensory test of the mungbean starch gel, its sensory scores for flavor and taste were highest in the 0.5% PSP to which mungbean starch gel was added.

  • Effects of concentration (5-8%, db) and heating temperature $(80^{\circ}C-95^{\circ}C)$ on rheological of mungbean starch were examined. The pasting curve by amylograph revealed no peak viscosity and the viscosity continued to increase during cooking, regardless the starch concentrations. Mungbean starch paste showed a pseudoplastic flow behavior with yield stress. The consistency index of paste increased as the heating temperature was raised at a given concentration. However, flow behavior index showed opposite trend. The percent sag of starch gel stored at $4^{\circ}C$ decreased with the increase of concentration and heating temperature. The firmness of fresh gel prepared from 7 and 8% starch suspensions by heating at $95^{\circ}C$ for 15 min with amylograph was about 2-times higher than that of 6% gel. However, the time constant, reciprocal of rate constant, of starch gels during aging at $4^{\circ}C$ was not significantly influenced by concentrations and heating temperatures.

  • This study was performed to develop a standardized recipe for yuza pyun made of citron juice that is by-product of citron tea, to increase the utilization of citron. The effects of mungbean starch(15%, 18%) and dilution ratio of yuza extract(100%, 75%, 50%) on the quality characteristics were evaluated. The quality characteristics of the samples were estimated in terms of sweetness, color difference, texture profile analysis and sensory evaluation. Sweetness of the 18% mungbean groups were higher than 15% groups(p<0.001). The values of Hunter color system indicated that higher content of yuza extract tended to increase yellowness significantly(p<0.001). Texture profiles of hardness, adhesiveness, springiness, cohesiveness, gumminess of yuza pyun showed no significant differences among samples. For sensory evaluation, color and sourness were decreased as yuza extract was diluted, whereas elasticity and sweetness were increased. Yuza pyun containing 18% of mungbean starch with 50% diluted extract was the most preferred in overall acceptability. According to multiple regression analysis, color, sweetness, elasticity and sourness(in order) were important control factors in overall acceptability.

  • This study was conducted to observe the effects of partial replacement of mungbean starch(MB) with dent(DT) or cross-linked(CL) corn starches, and of added hydrocolloids on the characteristics of mungbean starch and the mook. The replacement with CL caused less changes compared to that with DT in phase transition enthalpy of MB measured with defferential scanning calorimeter. The viscosity of MB paste cooled to $50^{\circ}C$ after heating was also affected less with CL than with DT. The addition of hydrocolloids to mixed starches of MB and CL did not affect initial viscosity increase but resulted in marked increase in viscosity at later stage of heating. Mixed monks with CL were more similar to MB monks than those with DT. Hydrocolloids added to MB-CL mixture further decreased the gap between monks with and without CL.

  • This study determined the effects of soybean oil$2\%$) and chitosan($1\%$) on the quality characteristics of Omija Jelly made of various starches (mungbean starch, cowpea starch and corn starch). RVA(Rapid Visco Analyzer) viscosity was measured for starches suspended in Omija aextract with $2\%$ soybean oil and $1\%$ chitosan. The color value, syneresis, texture(rupture test and TPA test) and sensory properties of the samples were measured. Gelatinization of cowpea starch was expedited by adding soybean oil and chitosan. Otherwise, gelatinization of mungbean starch and com starch was retarded by adding chitosan. The lightness(L) and the syneresis of Omija Jelly with soybean oil and chitosan were decreased, indicating the increased transparency and stability of Omija Jelly. Rupture stress and rupture energy of Omija Jelly were decreased by adding soybean oil. Rupture stress was increased and rupture energy was decreased by adding chitosan. The addition of soybean oil improved texture of Omija Jelly, indicating that the springiness, cohesiveness and chewiness of Omija Jelly were increased and adhesiveness was decreased. By adding chitosan, the springiness and hardness of Omija Jelly were increased and the cohesiveness and adhesiveness were decreased. The overall acceptability of Omija Jelly made of $6%$ or $7\%$ cowpea starch and com starch was increased by adding soybean oil and chitosan, but the quality characteristics of Omija Jelly made of mungbean starch were not influenced by additives such as soybean oil and chitosan.
